When OptiFine Standard for 1.3.1 out?

Quote from Leems_Segit

No I see what you mean. But when I spawned I was near snow, and in 5 minutes I went to some amazing place with big cliffs and stuff.

Quote from Swimmer1929

Hm... What version of Minecraft are you running? If it's 1.3.1, then Regular and light won't work (they are for 1.2.5). You'll need to get Ultra (Don't worry, it's better than the regular ). If you are running 1.3.2, then Optifine hasn't been updated for it yet. If you are running 1.2.5, then I dunno.

Quote from IronWill1991

Use Ultra and keep AA and AF off and set chunk loading on default then you got yourself standard.

Quote from bozworths

posting again, I did ultra with 1.3.1 and still no dice. When I create a new world it says building the chunks, yadda yadda, but when it goes to load it the screen goes black and then I get a crash report. Anybody have any advice?

Information for Texture Pack Authors (based on MCPatcher's description)

HD Textures
For the most part, you create an HD texture pack the same way you create a non-HD one. This thread has a list of the files in a typical texture pack.

Texture files within a pack can be different sizes. OptiFine uses the size of terrain.png and gui/items.png as a base and scales the custom textures up to that size. This means that a 32x custom water and 128x custom lava textures will be scaled to 64x when used with a 64x terrain.png.

Custom Animations
Custom animations are read from these files, all in the anim/ folder of the texture pack .zip (root folder also works):

• custom_water_still.png, custom_water_flowing.png - still and flowing water
• custom_lava_still.png, custom_lava_flowing.png - still and flowing lava
• custom_portal.png - portal animation
• custom_fire_n_s.png, custom_fire_e_w.png - the north-south and east-west sides of fire blocks, respectively
• custom_terrain_###.png - animation for any tile in terrain.png. ### is the tile index (0-255), not a block or item ID
• custom_item_###.png - animation for any tile in items.png. ### is the tile index (0-255), not a block or item ID

Each image should be a vertical strip of separate frames. The width should match the tile size of the texture pack, but if it doesn't it will be resized to match. See this thread for a more detailed explanation.

Each custom animation may also specify its animation speed and frame order. Create a text file with the same name as the animation but change .png to .properties. In the file, make a series of entries

tile.X=Y
duration.X=Z

X starts at 0 and represents the order you want frames to display in. Y in the tile number in the animation .png file. The first tile is 0, the second is 1, etc. Z is the duration you want that frame displayed, in game ticks (if omitted, duration is assumed to be 1 for that frame). For example, to make an animation with 3 tiles, run on a 5-frame animation with a pause in the middle, the .properties file might look like this:

tile.0=0
tile.1=1
tile.2=2
duration.2=5
tile.3=1
tile.4=0

You may also create a custom animation for any texture in the game. Create a .properties file in the anim/ folder of your texture pack. In it, supply the source and destination texture, along with coordinates of the area you wish to animate. The following example animates the first painting in kz.png.

from=/anim/mypainting.png
to=/art/kz.png
x=0
y=0
w=16
h=16

from is the location of your custom animation. to is the texture you wish to animate. x, y, w, h are the coordinates of the rectangular area of that texture. The width of the from texture should be equal to the value of w; if not, it will be scaled automatically. You can have many different animations applied to the same texture by creating separate properties files for each. The properties file can also contain tile order and speed information as described above.

Random Mobs
You may include multiple skins for the same mob and the game will automatically pick one at random. Add a number to the end of the filename before the .png, e.g., /mob/creeper2.png. Start at number 2 and do not skip any numbers. For the wolf textures, make sure you include the same number of wolf, wolf_tame, and wolf_angry textures or it will look strange when a wolf changes moods.

HD Fonts
To configure the widths of individual characters create a text file called /font/default.properties or /font/alternate.properties. Each line in this file specifies the width of a character:

width.<ascii value="" 0-255="">=<width 0-8="">

For example, to specify the widths of capital A, B, and C, you might use

width.65=5.9
width.66=5
width.67=5.25

Values can be floating point numbers (Notch's original code only supported integer widths) and range from 0-8 regardless of the resolution of the font. You do not need to specify widths for all characters, only ones where you want to override the default width.

The space character has a default width 2. However you can override this the same way, by setting width.32 to a custom value.

Nuin has created an Excel spreadsheet to make the font calculations easier. Also see his Berylium font.

Custom Colors (sample color.properties)
The CustomColors allow texture pack authors to customize many of the games hardcoded colors. Here are the files you will need to include in the texture pack:

/color.properties:
This text file allows you to specify colors for potions, spawner eggs, lilypads, and a base color for water particle effects (drops, splashes, and bubbles). A template file with the game's default values is available here. See the # comments above each value for a description of how it is used in game.

/misc/redstonecolor.png:
This is a 16x1 bitmap used for redstone wiring and particle effects. Other redstone colors (torches, repeaters, etc.) are still in terrain.png / items.png as usual. The x-axis of the redstonecolor.png bitmap represents the current strength. 0 is fully off, 15 is fully on.

/misc/stemcolor.png:
This is an 8x1 bitmap used for pumpkin and melon stems at each growth stage. 0 is a sprout, 7 is fully grown.

/misc/lavadropcolor.png:
This is a bitmap used for the lava drop particle effect as it cools during its fall. The height should be 1 pixel but the width can be anything. The x-axis represents the particle's age in game ticks (about 1/20th of a second). Lava drop particles are generally not visible for the first 40 ticks or so because they start out embedded in the block above. 90 pixels is a good width. If the particle lives longer than the width of the image, the last pixel is used for the remaining time.

/misc/myceliumparticlecolor.png:
Used for the particle effect created by mycelium blocks. This image can be any size. A random color is chosen from this bitmap for each new particle.

/misc/xporbcolor.png:
Used for the experience orbs. This image can be any size. The color chosen will move in a sinusoidal pattern from (0,0) to the end of the image. The speed of the sine wave is slowed down by a factor of 4 to allow texture packs to have slower pulsing xp orbs than the default. If you want to keep the default speed, simply copy your image 4 times vertically.

/misc/swampgrasscolor and /misc/swampfoliagecolor:
256x256 biome palettes used in swampy areas. They work just like their non-swamp counterparts.

/misc/pinecolor and /misc/birchcolor:
Biome color palettes for pine and birch leaves. The pixel at (127, 127) is used for the default color when the block is held or in inventory.

/misc/watercolorX.png:
Biome color palette for water. Note the capital X in the filename to prevent the default watercolor.png from being used accidentally.

Other biome palettes:
You can also assign a custom biome palette to any standard block. Here "standard" means any block that does not already have its own special coloring. In MCP terms, this is any Block subclass that does not override the colorMultiplier method. Create a 256x256 bitmap, then in color.properties add a line

palette.block.<path>=<list of="" block="" ids="">

For example, to use /misc/stonecolor.png with all stone and ore blocks, use

palette.block./misc/stonecolor.png=1 14 15 16 21 56 73 74

To further restrict the palette by block metadata, use the syntax <id>:<metadata>, e.g., 43 would affect all double slabs, 43:1 would apply to only sandstone double slabs.

/environment/lightmap-1.png: (Nether)
/environment/lightmap0.png: (Overworld)
/environment/lightmap1.png: (The End)
These are custom lighting palettes for each world. The height must be exactly 32 pixels but they can be any width. Each bitmap actually consists of two palettes, but we'll get into that later.

First an explanation of how lighting normally works in Minecraft. Every block has two light values from 0 to 15 assigned to it, one for sky brightness and one for torch brightness. A block in direct sunlight has a sky value of 15. A block in the shade directly adjacent to it has a value of 14 and so on. Blocks deep underground far from any block that can see the sky have sky brightness 0. Similarly for torches. A torch block has light value 14 and the light value drops by 1 each block away from it.

To generate the lighting you actually see in game, Minecraft uses a 16x16 lightmap. Its axes correspond to the 16 light levels of each type. If a block has torch brightness x and sky brightness y, it uses (x,y) for its lightmap coordinates. The lightmap is not in any of the game's files but is generated each frame. You may have found that light_normal.png file in minecraft.jar, but it is not used at all. Two variables affect the lightmap, the time of day and the torch flicker. Minecraft implements night and day and torch flicker by making the entire lightmap darker or lighter rather than by adjusting the sky/torch brightness values.

Remember your palette must be exactly 32 pixels high, but can be any width. The top 16 rows represent sunlight and the bottom 16 represent torchlight. Two columns, 16 pixels from the top half and 16 pixels from the bottom half, are chosen to form the axes of the final 16x16 lightmap used for rendering.

In the top half, the left-hand side represents night and the right-hand side represents day, with the dusk/dawn transitions in between. The very far right of the palette represents lightning flashes. There is no specified width for the palette, but more width means more room for detail in the dusk/dawn transitions.


Blue=night, orange=dusk/dawn, cyan=day, yellow=lightning. (Template by Misa.)

Torches work similarly, but in this case x is a random value based on the torch flicker.

The method described above is used for all three worlds (Overworld, Nether, The End), but since there is no night or day in Nether and The End, the "time of day" value is constant. For these worlds you can simply give each row 0-15 the same color all the way across.

Connected Textures (sample ctm .properties)
ConnectedTextures is compatible with the original CTM mod, so if a texture pack already follows the /ctm.png standard, it should just work. Here's the template /ctm.png from the original thread for reference.

In addition, you can use connected textures with any block. The format is the same as above, but just the glass part. Here's a template with simple black outlines.

Both block-based and tile-based methods are supported. Name the file /ctm/block<block id>.png or /ctm/terrain<tile number>.png depending on which you want to use. Also remember that the image needs to be the same size as terrain.png (256x256 for 16x texture packs, etc.).

You can also specify multiple ctm blocks from the same image. Create a file called /ctm/block<block id>.properties or /ctm/terrain<tile number>.properties. In it, specify the name of the source image and the list of tiles to use. There must be exactly 48 tiles listed:

source=/ctm/myctm.png
tiles=64-75 80-91 96-107 112-123

See this sample texture pack for an example. It applies CTM to dark red, greed, blue, purple, and cyan wool using the same image.

You can also use the .properties file to specify random textures or repeat a larger pattern over several blocks. See the sample .properties file here for more information.

The default fog settings in Minecraft are quite bad.
On all distance settings except FAR the game looks foggy with washed-out colors, especially bad on tiny/short.
It may be moody for winter biomes, but irritates everywhere else.
Also Optimine for 1.4_01 was not really working for me, so I decided to fix the problem myself.

What the mod does:
1. Pushes the fog away from the player so that it is only visible as transition on the render limits => looks better
2. Uses a fast fog type on FAST and a better looking fog type on FANCY settings => FPS boost
3. Decreases the render distance a little to get the same visible depth as before. On FAST decreases it even more to compensate for bad fog on screen edges => FPS boost
4. Added experimental Occlussion Culling (hidden geometry removal) so only visible objects are rendered. Helps a lot on bigger render distances, on FAR and NORMAL doubles the FPS.
5. Added Optimine compatible versions (both "inio" and "303" versions of Optimine).
6. Added Texture mipmapping - far distances blend nicely, no more eyestrain.
7. Added chunk loading optimizations, like mod CAF. Configure how much chunks are to be loaded and how fast, define "loading free" walking distance, limit max number of loaded chunks, fast render distance switching without reloading chunks.
8. Modular and configurable. Install only the functions you need. Edit configuration file to turn on/off functions or change parameters. See "Readme.txt" and "optifog.txt" for details.

The original fog starts too close to the player and everything is rendered foggy, especially on short render distances. After correcting the fog more terrain is visible, which is compensated by decreasing the render distance which increases FPS. Plain 1.4_01 always uses the better looking fog type if available, which is SLOW. The mod uses a faster fog type on FAST which is 80% faster on my PC.

The Occlusion Culling (hidden geometry removal) is still experimental. If it is works then the results should be pretty dramatic, my FPS on NORMAL and FAR is doubled :-). OC is currently tested on nVidia. I suspect that some ATI cards may have problems with it. Please, check for visual artifacts and report back.

The Optimine version was a dog to get running, but it is all over. Finally!

Classic is updated to better render the sunrise/sunset on FAST.

The mipmapping version may steal 2-3 FPS but the result is nice. Minecraft is finally looking good.

The chunk loading optimizations allow to fine tune the chunk loading so that is does not get in the way. Also fast render distance switching without chunk reloading is possible (like mod CAF).
Added dynamic chunk update rate. When the player is staying still it uses fast update rate to load the map faster, when the player is moving (movement, mouse, actions) uses minimal update rate to keep the FPS high.

See "Readme.txt" and "optifog.txt" for more details.

With the fog away, even shorter render distances look good and are playable.

Tips and tricks:

1. Download the latest Java 7 builds from here: http://download.java.net/jdk7/. Minecraft should run much smoother with less lag spikes. It really helps.
2. Set the Java process to higher priority
3. Set "Limit framerate" to Max FPS. The limiter is so implemented that it always decreases the FPS.
4. Update LWJGL from here.
5. Lauch Minecraft with less memory (yes, really). It needs maximum 256 MB and runs fine on all settings with the default texture pack. By default java allocates too much memory (1GB?) which may get swapped to disk and the overall performance may suffer a lot. To start Minecraft with less memory:

• Download and start the Magic Launcher.
• Click Setup
• Enter 256 in the field "Memory"
• Click OK
• Login and play
